Description
Technical field
The present invention relates to tire or conveyer belt production technical fields, and in particular to a kind of aramid fiber surface treatment fluid and its
Preparation method.
Background technology
Aramid fiber is succeeded in developing from the sixties in last century by du pont company, and in the commercialization seventies, due to it
The advantages that high intensity itself, high-modulus, is applied to the fields such as bullet-proof vest, fire-entry suit, aerospace, framework material.But
Aramid fiber strand arranged regular and active function groups are few, causes its bond properties between basis material very poor, greatly
Ground limits its application in terms of framework material.
Aramid fiber be it is a kind of formed by rigid molecule chain, there are high intensity, high-modulus, high temperature resistant and the deformation superiority such as small
The new special High performance industrial fiber of energy.However aramid fiber has unique " Pi Yixin " structure, core leans on hydrogen by many
The rodlike molecule of key connection is formed, and epidermis is formed by the high rigid molecule chain of crystallinity along fiber axial alignment, and thickness is about
The 1%-40% of only entire fibre diameter.Again since aramid fiber molecular structure belongs to phenyl rigid molecule, phenyl ring is to phthalein amine official
Hydrogen atom on rolling into a ball has shielding action so that fiber surface lacks activity, and hardly possible forms chemical covalent bonds, and benzene on interface
The steric effect of ring, is hardly formed hydrogen bond so that surface lacks chemical active radical, and surface is smooth, and interface adhesion is poor, makes
Composite material interlayer shear strength is low.These situations limit the performance of material superiority, excellent in order to give full play to aramid fiber
Mechanical property, it is necessary to be modified processing to aramid fiber surface, to improve the interface bonding state of aramid fiber enhancing composite material.
At present, aramid fiber surface modified method mainly has:Plasma surface modification technology, ultrasonic wave force infiltration skill
Art, gamma radiation method, chemical grafting treated method etc..
Plasma surface modification:The radical reaction for triggering aramid fiber using plasma carries out.By plasma
Trigger the free radical generated followed by reactions such as cracking, radical transfer, oxidation, disproportionation and lotus root conjunctions.
Ultrasonic wave forces imbibition technique:Mainly using ultrasound cause in a liquid generated during the rupture of bubble high temperature,
High pressure and local shock effect cause the variation of thermoplastic resin-impregnated fibers.
Gamma radiation method:Surface grafting and fibrous inside fento cross-linking reaction are carried out to aramid fiber using mono- rays of Y,
It is that a kind of new improved technology, this method are not required in recent years so as to improve the method for fiber bodies intensity and its wetability
Catalyst or initiator can be reacted at normal temperatures, be a kind of rising modification technology.
Chemical grafting treated method:Chemical modification method is using chemical reaction, and reactive group is introduced in fiber surface,
So as to generate covalent bond with matrix compound tense, increase the interface performance of material.Its method is generally divided into surface etch, coupling agent
Modified and surface grafting.
But when above method is modified, there are following problems:Investment is big, and reaction condition is high or needs the reaction participated in
Object is more, and consersion unit is more, and interfacial bonding property is poor.
The present invention is on the basis of forefathers study, and by changing the processing method of aramid fiber, reaches and improves aramid fiber fibre
The bond properties of dimension, the purpose for widening its application field.
